The specific embodiment
Below by preferred embodiment and accompanying drawing the utility model same table is elaborated.
Consulting Fig. 2, Fig. 3, is a preferred embodiment of the utility model same table 3, comprises that a table 4, is connected with a foot rest unit 5 and the adjustment unit 6 in table 4 bottom surfaces.Table 4 is provided with a perforation 41 (as shown in Figure 8) that runs through its end face and bottom surface.Wherein foot rest unit 5 has two in order to be placed on ground stand 51 and two adjustable shelfs 52, each stand 51 has a bottom bar 511, two and is located at bottom bar 511 respectively near the place, bottom surface at two ends and in order to the upright at interval support bar of being located on the bottom bar 511 513 of the runners 512 and two of kiss the earth, each support bar 513 is hollow tube, and the top is open shape.Each adjustable shelf 52 then has the standpipe 522 that a upper frame body 521 and two is convexly set in upper frame body 521 bottom surfaces and extends downwards, each standpipe 522 also is a hollow tube, the bottom is open shape, and the upper frame body 521 of two adjustable shelfs 52 respectively is provided with a locating hole 523 (as shown in Figure 7) in corresponding position.In addition, each standpipe 522 can be in order to be inserted in each support bar 513.
Consult Fig. 3, Fig. 4, adjustment unit 6 comprises two sleeves 61, two that are hollow form be spirally connected bar 62, two pedestals 63, a plurality of helical gear 64, a connecting rod 65 and a rocking handle 67 (as shown in Figure 8).Each sleeve 61 internal face forms negative thread 611, and the top also is open shape.And each bar 62 outer peripheral edges face that are spirally connected forms the pin thread 621 that can cooperate bridle joint with the negative thread 611 in the sleeve 61, be spirally connected bar 62 tops and be provided with one can be in order to the axis part 622 that is connected with a helical gear 64.In addition, pedestal 63 has a body 631, body 631 has a plurality of sidewalls 632 and and defines the accommodation space 633 that forms by described sidewall 632, all offer a through hole 634 on each sidewall 632, make that described through hole 634 can be towards different azimuth (as up, down, left, right, before and after etc.), pedestal 63 also has a plurality of cover plates 635,636 in order to seal each through hole 634 on each sidewall 632 that are locked on, and respectively this cover plate 635,636 is provided with a perforation 637,638.Having a tooth portion 641 and as for 64 of each helical gears can be by the protruding axial region 642 of corresponding through hole 634 with perforation 637 (638), and protruding axial region 642 1 ends also are recessed to form an engaging groove 643 inwardly, and engaging groove 643 is polygon.And the shape of the axis part 622 of the bar 62 that is spirally connected, connecting rod 65 is all corresponding with the shape of engaging groove 643.
Consult Fig. 4, Fig. 5, Fig. 8, when combination, each helical gear 64 is to utilize its protruding axial region 642 to run through perforation 637,638 on through hole 634 and each cover plate 635,636 on each pedestal 63, and borrow a C type cramp 66 to be buckled on the protruding axial region 642, can make described helical gear 64 integrated positionings on each cover plate 635,636, the tooth portion 641 of helical gear 64 also stretches via through hole 634 and to place accommodation space 633.The cover plate 635,636 that will be combined with helical gear 64 more is locked on the sidewall 632 of pedestal 63, finishes the combination operation of helical gear 64 and pedestal 63, this moment each helical gear 64 engaging groove 643 and be revealed in cover plate 635,636 outer surfaces.What specify is, pedestal 63 in the present embodiment is not all helical gear 64 must be installed on each sidewall 632, but can according to required decision helical gear 64 orientation and number be set for personnel.
Then the axis part 622 on bar 62 tops that are spirally connected can be connected with downward opening engaging groove 643, when making helical gear 64 rotations that are connected with the bar 62 that is spirally connected, interlock bar 62 rotations that are spirally connected simultaneously, under the negative thread 611 of be spirally connected 61 in bar 62 and sleeve drove with pin thread 621, bar 62 sleeve 61 telescopic displacements relatively were spirally connected.So far promptly finish the be spirally connected assembling of bar 62, two pedestals 63, a plurality of helical gear 64 and connecting rod 65 of sleeve 61, two.
As Fig. 2, Fig. 3, shown in Figure 8, again sleeve 61 parts are inserted in the support bar 513, and utilize the screw location that locked, standpipe 522 with adjustable shelf 52 is placed on outside the sleeve 61 simultaneously, and standpipe 522 is also further stretched and is placed support bar 513, be arranged in the pedestal 63 on bar 62 tops that are spirally connected and stretch the upper frame body 521 that places adjustable shelf 52 this moment, the engaging groove 643 of pedestal 63 upper sheds helical gear 64 up also is revealed in upper frame body 521 outer (as shown in Figure 6), after follow-up table 4 is installed on the upper frame body 521, the engaging groove 643 proper communicate with the perforation 41 of table 4 (consulting Fig. 8) of pedestal 63 upper sheds helical gear 64 up.In addition as shown in Figure 7, two pedestals, the 63 upper sheds locating hole 523 on the upper frame body 521 of the engaging groove 643 of the helical gear 64 of left and right (direction as shown) and alignment activity frame 52 respectively.
Consult Fig. 7, connecting rod 65 is 52 of two adjustable shelfs that are arranged at foot rest unit 5, the two ends that also are about to connecting rod 65 are respectively by the locating hole 523 on the upper frame body 521 of two adjustable shelfs 52, and then be connected with the engaging groove 643 of corresponding helical gear 64, can make the helical gear 64 that is positioned at connecting rod 65 both sides produce continuous action relations whereby.In addition, as shown in Figure 8,67 of rocking handles are to have a shape and each engaging groove 643 corresponding axis parts 671.
Consult Fig. 8, Fig. 9, the utility model same table 3 is in the time will carrying out Height Adjustment, as long as the axis part 671 of rocking handle 67 is inserted in the perforation 41 of table 4, and then be embedded in the engaging groove 643 of opening helical gear 64 up, rotation rocking handle 67, helical gear 64 rotations that can be connected by axis part 671 interlocks of rocking handle 67, and then interlock and other helical gear 64 rotations of bridle joint mutually of described helical gear 64, synchronous interlock bar 62 relative each sleeve 61 telescopic displacement that respectively are spirally connected, the synchronous interlock effect that transmission produced by connecting rod 65 simultaneously, and then make each adjustable shelf of each pedestal interlock drive table 4, make table 4 under the flexible drive of the bar 62 that is spirally connected, to rise, displacement is fallen.Again when table 4 has reached suitable height, the user more rocking handle 67 can be got from, so can not influence personnel's the activity and the available zone of desktop.
Please consult Fig. 9 again, the utility model same table 3 also can be provided with screw (not shown) at the body of rod place of sleeve 61, stand 51 respectively, the user can directly be sheathed on sleeve 61 stand 51 bottoms, also sleeve 61 can be positioned stand 51 screw place (bottom of Fig. 9 middle sleeve 61 suitable away from stand 51 bottom surfaces) is set, with under the certain situation of bar 62 length overalls that are spirally connected, same table can be risen to higher height, and save material cost.
As above-mentioned, the utility model same table 3 is by above-mentioned structure design, when adjusting table 4 height, as long as rotation rocking handle 67 can drive table 4 liftings easily, quite convenient in the operation, and when table 4 has reached suitable height, rocking handle 67 also desirable from, so can not influence personnel's the activity and the available zone of desktop, in addition, adjustment unit 6 volumes in order to 4 liftings of control table are little, do not have complicated interlinked mechanism again, therefore can also reduce manufacturing cost.
